Topic: DS Rennet - MATH HELP (Read 1907 times)

My mind can not handle such analytical things anymore I guess. Went back to my algebra to try figure out what should be a simple linear equation and I got lost.

I obtained 1 fluid ounce of double strength rennet from a dairy out here in WI. I looked at the label an is says: add 1 OUNCE to 1,000 POUNDS of milk.

I know know a gallon of milk weighs 8.6 lbs. Need help with fining out how much of a TSP per gallon should be used.

P.S. The only reason I am doing this is because I'm not too sure if Double Strength means use HALF to achieve the same results as single. Lastly, I don't know if thestuff is calf or vegetable DS rennet.

By my crossbred calculation, that would be 0.2ml per gallon. My DS calf rennet, according to the label, recommends a max. of 1.25ml per 10l milk, that is 0.5ml for 4l (=approx 1 gallon). Why not a small make, say 4l(1 gallon) and see what happens - if its really slow to coagulate then you know you need more. Margaret

Yes, double strength means use half as much. Rennet recommendations are just that: recommendations. Different milks, etc will all change things slightly but halving the rennet amount in the recipe should do the trick.

I was never good at math. English was my forte.

Running through my Excel I came up with this:

1000 lbs/8.6 lbs = 116.27 =~ 116 gallons

116 gallons/4-gallon batches =~ 29 4-gallon batches

1 oz = 29.6 ml = 6 tsp

29 ml for 29 4-gallon batches

~1 ml for each 4-gallon batch

double strength rennet => ~1/2 ml for each 4-gallon batch

I'm sorry if that doesn't make any sense. I don't use liquid rennet, but instead rely on dry calf rennet.

Start off using about 1/4 tsp for 4 gallons. In order to improve accuracy I counted the number of drops in 1/4 teaspoon (approx 20 using my bottle dispenser) and adjusted the amount I was using based on the flocculation time I was getting. I have single strength veal rennet and use 1/4 tsp for 2 gallons (adjusted to 22 drops).
